What is ectropion? Ectropion is an abnormality of the eyelids in which the lower eyelid rolls outward or is everted. This causes the lower eyelids to appear droopy. Ectropion exposes the delicate conjunctival tissues that line the inner surface of the eyelids and cover the eyeball, causing drying of the tissues, resulting in conjunctivitis.
Ectropion can be caused by: 1  Muscle weakness. As you age, the muscles under your eyes tend to weaken, and tendons stretch out. These muscles and tendons hold your eyelid taut against your eye. When they weaken, your eyelid can begin to droop. 2  Facial paralysis.
